.box {
box-sizing: content-box:
width: 100px;
height: 100px;
padding: 20px;
border: 5px dash blue;
}
The element with the class .box would have a content area of 100px by 100px. This picture visualizes the concept. So yes it should be the case.

38,489 PointsDo ALL elements (including inline and block) in HTML come with padding and margin by default?
That depends on your user agents style sheet, which you can override with a css reset.
Hmm okay. So would you say that all elements are originally just their content box, except once padding and margin are applied to them?
If box-sizing is set to content-box, that is correct.

38,489 PointsIf not explicitly defined like in the above example, yes. The browser and many other markup based graphic frameworks, like WPF for windows apps, go down the markup tree, in the case of the web your html, try to get the space each child needs and then adapt the parents size accordingly.
